The effect of a continuing medical education program on Venous thromboembolism prophylaxis utilization and mortality in a tertiary-care hospital

摘要

Background Venous thromboembolism (VTE) prophylaxis is underutilized for hospitalized patients. The primary objective of this study was to assess the impact of a continuing medical education (CME) program on thromboprophylaxis and VTE-associated mortality in a tertiary-care hospital. Methods This was a retrospective study of all patients admitted to a tertiary-care hospital from 01/07/2009 to 30/06/2010 (after a CME program that aimed at improving VTE prophylaxis) and had confirmed VTE during stay. VTE prophylaxis utilization and associated mortality were assessed in them and compared to those of a similar cohort of patients hospitalized in the previous 12?months. Results There were 147 confirmed VTE cases in the study period (surgical: 26.5% and medical: 73.5%). Most (63.9%) VTE patients received prophylaxis after the CME program compared with 36.5% in the previous 12?months (relative risk 1.73; 95% confidence interval, 1.38-2.18; P??0.001). More surgical (82.1%) than medical (57.4%) patients received prophylaxis (P?). VTE-associated mortality rate was 10.9% with a significant decrease after the CME program (relative risk, 0.52; 95% confidence interval, 0.30-0.90). This mortality was lower for those who received VTE prophylaxis compared to those who didn’t (4.3% and 22.6%, respectively; P?). Additionally, VTE-associated deaths represented 1.1% of total hospital mortality compared to 1.9% in the 12?months before CME program (relative risk, 0.58; 95% confidence interval, 0.32-1.04; P?=?0.07). Conclusions A CME educational program to improve VTE prophylaxis in a tertiary-care hospital was associated with improvement in VTE prophylaxis utilization and VTE-associated mortality. Such programs are highly recommended.
